This invention concerns a ladder bracket and clamp for holding a scaffolding ladder in upright position adjacent the wall of a building.

It is a major object ofthe invention to provide a ladder bracket and clamp which may be attached to the side of the building and will support itself in proper position while a scaffolding ladder is raised or lowered to its proper place.

Another object of the invention is to provide a self-supporting ladder bracket which may be folded flatly for purposes of handling and storage.

A further object of the invention is to provide a ladder bracket and clamp which is capable of holding a ladder on porting arm.`

A still further object of the invention is to provide an improved ladder bracket which is of simple construction and may, therefore, be Aeconomically fabricated from standard materials.

Other objects and advantages ofthe invention will become apparent from the following speci'- cation taken in connection with the accompanying drawing, wherein:

Figure 1 is a perspective view of a ladder clamping bracket embodying the invention and shown positioned on the wall of a building and holding a ladder;

Figure 2 is a top plan view of the ladder bracket shown in Figure 1 Figure 3 is a side elevation, with the clamping member removed, of the ladder bracket-shown Ain Figure 1; Figure 4 is a front elevation, with the clamp-l ing member removed;

Figure 5 is a front elevation showing the ladder bracket in folded position, the clamping member being removed for purposes of clearness, and y p Figure 6 is a top plan View of the ladder bracket in folded'position. -f Y According' to the invention in its preferred form, the ladder bracket has-a wall engaging fixture provided with a pair of mutually perpendicular arms which carry a ladder supporting arm extended outwardly from the fixture. The ladder supporting arm may be pivoted to the fixture so it can be folded flush therewith during transportation and storage. The ladder supporting arm is provided with an elongated slot through which extend threaded end portions of a U-shaped clamp. With the fixture attached to the wall of a building and the ladder supporting arm extending outwardly, a scaffolding ladder may be raised or lowered between the clamp and the ladder supporting arm until it is propeither side of its ladder sup- 2 Claims.

erly positioned. By tightening the clamp, the ladder is secured and retained in proper position with respect to the Wall.

Referring now to the embodiment of the invention shown in the` accompanying drawings, a wall engaging fixture designated generally at II is provided with mutually perpendicular arms I2 and I3 formed of angle iron. The arm I2, referred to as the wall engaging arm, has a pair of projections I4 and I5 extending upwardly therefrom. Each of these projections is provided with a bayonet slot I6 for securing the xture on screws or nails II embedded in the wall of the building. For purposes of rigidity, a brace I8 may be arranged between the two arms I2 and I3 and have its ends secured to them respectively. Y

' A ladder supporting arm designated generally at I9 is formed of strap material having one end pivotally connected as by rivet 2I to the horizontal flange of the angle iron forming wall at- The .strap iron of the ladder supporting arm I9 is folded upon itself at 22, and the other end'is secured to the fixture II. In the drawing, this other end is shown as-being secured to a shelf 23 on one flange of the angle iron forming steadying arm I3. The strap ma- 'terial is pivotally secured to the shelf 23 as by 'tends from the rivet 25 downwardly to form a brace 26, the end of which is secured by the rivet 24 to shelf 23. 1`

i In order to permit the ladder supporting arm I9 to be folded flush with the xture I I, the rivets 2| and 24 may be loosely tted so the entire ladder supportingarm may turn about an axis par'- allelto'th'e steadying arm I3. To hold a ladder in position, a U-shaped clamp 2l has its end portions 28 and 29 extending through the elongated slot 20 between the upper and lower strap portions of arm I9. The U-shaped clamp 21 is shaped to surround the ladder and has threaded ends 3| and 32 provided with wing nuts 33 and 34, which engage the sides of the strap member I9 to retain the clamp 21 and tighten the clamp on the ladder. To maintain the formation of the elongated slot 21, a spacer 35 may be positioned between the folded portions of the strap material and intermediate the ends of ladder supporting arm I9. This spacer 35 also serves to prevent the member 21 from sliding out of the slot when it is not supporting a ladder.

Sometimes it is desired to hold a ladder on each side of the ladder supporting arm. In other cases, it is desirable to have an option as to which side of the ladder supporting arm a ladder will be placed. To take care of such contingencies, a second U-shaped clamp 3'I has one end portion 38 extending through the slot 20 and its other end 39 extending through a slot 4I formed by a strap member 42 secured beneath the upper folded portion of the strap .forming the ladder vsupporting arm I9 adjacent the iixture II. Rivets 43 and 44 may hold the strap member 42 in position.

In order to retain the ladder supporting arm` I9 in position perpendicular to the arms I2 and I3, a detachable brace 46 has one 'end pivoted as by the rivet 25 to the ladder supporting arm I9. Its other end may be secured to the upper ange of wall engaging arm I2 as by a bolt 4l' and a wing nut 48. In order to fold the ladder Asupporting arm I9, the wing nut 48 is removed,

the bolt `lll withdrawn, andthe arm 46swung to a position coincident with 'the ladder supporting arm I9. The ladder supporting 'arm may then be turned about its pivots. 2l and 2'4 to `a position '.iiush with the fixture II as lshown .in Figures 5 and 6.

In 'erecting a scaffold, the ladder bracket is vattached to a wall by vsuitable devices such as bayonet slots IE and bolts I'I. The ladder supporting arm I9 may then be secured in position by connecting the brace 46 to the wall attaching arm I2 as by the kbol't 41 and wing nut- '48. A ladder isA then raised to the desired position on either side of the laddersupporting arm' I9, and the wing nuts on the ladder clamp :2l or '3l are tightened to clamp and hold the ladder between the clamp and the, ladder rsupporting arm, .To remove the ladder, the wing; nuts on the clamp are loosened, the ladder lowered, and the rfixture readily removed from the wall by sliding *the bayonet slots I6 over the headsv of boltsl l1.
